Re: [Done] CommonSense: matrix LCR meter with a HID interface

The extra grounding worked great. Everything registers now. I'm typing this on the Harris as I speak. The repeating pressed #16 16 shows up every time I use the upload function. Afterwards, it will still commit and write to the EEPROM but I have to physically disconnect and reconnect the board for i...

Re: Deskthority Awards 2019 ~ Phase 1: The nominations

I nominate DMA for best project for the Magnetic Valve switch conversion added to Commonsense this year. It made a new legion of beautiful boards usable again on modern PC's.

I know he won last year, but this is different enough to be considered another project I think?

Re: Mini Mechanical Keyboard with Magnet - Custom Value and Macro

Looks like the magnetic bottoms are snap-in. If that's the case, anything with a cherry compatible plate and pinout should work. Plus they got box switches in the example picture.

Aren't they just carbon doped plastic all the way through? I could have sworn it was still black when I saw a busted one in my old blue switch.

This is the Harris, which you noted might need extra grounding at a couple points to pick up a couple columns. Those I think are the ones not triggering. I'll have an hour or two to fiddle with it tonight and I'll report back. Settings right now are Debounce 8, Threshold 10 (though up to 20 works th...

It wouldn't bug me much if they weren't the rare magnetic reed variant. I love the old foam and foil myself, but it ain't the end of the world if someone used one of those for some silly project like that instead.

New old stock is amazing. Wish my case was still that white instead of a tad yellow. I've been using mine as a daily driver since May and it's great. Gotta say I like the white case more than black though. One thing you forgot to mention between this and the 3rd Gens is that these don't have the dio...

Re: Best replacement foam for keytronic foam and foil switches

Different switch types probably had different thicknesses. The 1978 block style keytronic I'm working on right now seems like it had around 2mm pads instead of the 4'ish of the 1980's tall single switch models.

Yeah, these are all 3rd Gen leaf springs IIRC. Great boards. And unlike the 2nd Gen, they have all the diodes integrated already which makes converting so much better. With your matrix now, someone could actually convert one in less than an hour if they knew what they were doing. Really great work a...

Re: IBM Model M - Cleaning Membrane. Isopropyl / sterilized water / or?

Alcohol is the best option because it will dissolve grease and whatnot while leaving everything clean afterward. Dish soap and tap water will do the same job with a little more work.

You'll want some very fine sandpaper to clean any oxidized contacts in either case.

I like the sound. Nice and chunky. Seems like the closest thing in feel might be something like Futaba MD? I kinda wished you'd made some more comparisons besides the SKCM one. Though that switch plate DOES look like it was yanked out of some kind of Alps.

Re: Fortune Systems looooong keyboard with Digitran capacitive switches (conversion)

The pads are the sense. The controller going crazy and had to be shot thing is because you hadn't dialed it in yet and when the whole keyboard is instantaneously sending keypresses at startup, it shuts the input down as a protective measure, but you can still adjust the values. Then once you do and ...

It's just rows to rows and columns to columns. Xwhatsit is already all set up for you if you use one. The Xwhatsit pdf has all the pins labeled.
